Transmigrating to the 1970s: The Cannon-Fodder Heiress Becomes the Army's Fiercest Rose

(1970s era + transmigrate into a book + space storage + medical skills + punishing scumbags + devoted couples + equally matched leads + military service + real and fake heiresses + defending the country) Lin Xiaoxiao, a medical genius from the twenty-second century, accidentally transmigrates into the impoverished 1970s and becomes the real heiress who was switched at birth and reduced to a cannon-fodder character in a book.

Worst of all, Lin Xiaoxiao's biological parents know she exists, but after her adoptive parents sell her to an old man, they give up on bringing her back.

They let things stand as they are, raising the impostor as their own daughter and no longer caring whether Lin Xiaoxiao lives or dies.

Newly transmigrated, Lin Xiaoxiao flies into a rage and immediately sends the adoptive parents who switched her at birth to prison!

She also signs up her two heartless younger siblings for rural service!

After dealing with this whole thankless family, Lin Xiaoxiao volunteers for rural service to support agricultural development. She helps the local villagers farm scientifically, raise Angora rabbits, and build a handicrafts factory.

When the college entrance examinations are reinstated, Lin Xiaoxiao takes one just for fun. Before she knows it, she's gone too far: a Navy combat frogman special operations unit recruits her, and she becomes a military rose whose name strikes terror into the enemy.

Just as Lin Xiaoxiao is thriving, the incredibly handsome man she once saved pulls her into his car in broad daylight. His gaze is sharp, his voice low. “Xiaoxiao, you saved my life. I have to repay you by giving myself to you...”
